Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

New Delhi, Jan 7: The Delhi Police has filed an FIR against JNUSU president Aishe Ghosh and 19 others for allegedly attacking security guards and vandalising the server room of the Jawaharlal Nehru University (JNU) on January 4.

The police registered the FIR on January 5.

In the complaint filed by the JNU administration, the University alleged that the accused were involved in physical violence and pushed the women guards, verbally abused them and threatened them of dire consequences if they opened the lock of university's communication and information (CIS) office.

"They illegally trespassed the University property with the criminal intention to damage the public property. They damaged servers and made it dysfunctional. They also damaged fiber optic power supplies and broke the biometric systems inside the room," the University officials alleged.

This incident allegedly occurred a day before Aishe Ghosh, other JNU students and teachers were attacked by a masked mob inside the campus.

New Delhi, Mar 10: A military transport aircraft of the Indian Air Force (IAF) brought back 58 Indians from coronavirus-hit Iran on Tuesday, official said.

The aircraft, a C-17 Globemaster, was sent to Tehran on Monday evening.

About 2,000 Indians are living in Iran, a country that has witnessed increasing numbers of coronavirus cases in the last few days.

"The IAF aircraft has landed. Mission completed. On to the next," External Affairs Minister S Jaishankar tweeted.

In an earlier tweet, he said, "First batch of 58 Indian pilgrims being brought back from Iran. IAF C-17 taken off from Tehran and expected to land soon in Hindon."

"Thanks to the efforts of our Embassy @India_in_Iran and Indian medical team there, operating under challenging conditions. Thank you @IAF_MCC. Appreciate cooperation of Iranian authorities. We are working on the return of other Indians stranded there (sic)," Jaishankar added.

The aircraft landed at Hindon airbase in Ghaziabad, from where the passengers were take to a medical facility.

According to latest reports, 237 people have died of novel coronavirus in Iran while the number of positive cases stands at around 7,000.

It is the second such evacuation by the C-17 Globemaster in the last two weeks.

On February 27, 76 Indians and 36 foreign nationals were brought back from the Chinese city of Wuhan by the aircraft of the Indian Air Force.

The C-17 Globemaster is the largest military aircraft in the IAF's inventory. The plane can carry large combat equipment, troops and humanitarian aid across long distances in all weather conditions.

Four days ago, a Mahan airline plane brought swab samples of 300 Indians from Iran to India.
